Abstract: The invention is a method and an apparatus for marking an article and the article thus marked. It includes providing the article. Generating a plurality of groups of laser pulses. At least one of the plurality of groups is generated by modulating a beam of laser pulses to form a plurality of beamlets. Each, of the plurality of beamlets, include at least one laser pulse. It also includes directing the plurality of groups of laser pulses onto the article such that laser pulses within the at least one of the plurality of groups impinge upon the article at spot areas that do not overlap one another, wherein laser pulses within the plurality of groups are configured to produce a visible mark on the article.
